A method is described for quantitative analysis of the pyrimidopurinone adduct (M1G) arising from reaction of malondialdehyde (MDA) with DNA. DNA samples treated with MDA are reduced with sodium borohydride and hydrolyzed with 0.1 N HCl. The bases released are isolated by solid-phase extraction and analyzed by high-performance liquid chromatography with(More)
A method is described for detection and quantitation of the major malondialdehyde-guanine adduct (M1G) based on thermospray liquid chromatography/mass spectrometry. A stable isotope analog of M1G ([2H2]M1G) was used as an internal standard. Thermospray mass spectra of M1G and [2H2]M1G showed intense protonated molecular (MH+) ions that were suitable for use(More)
